Specification of Letters Patent.

Application filed August 21, 1908. Serial No. 449,698.

Iowa, have invented certain` new and user-ullmprovements inFertilizer-Distributors, of which the following is a specification.

My invention relates to improvements in fertilizer distributers, and theobjects of my improvements are these: First, to providesuitable'mechanism for returning` the conveyer-apron to its initialposition when it has arrived at its limit of discharging movement;second, to furnish means for horizontally adjusting the spacing apart ofthe Vdriven gear on the ends of the transverse operating-shaft in orderto accommodate` the i m to any one ot various widths of wagon oxes orrunninggear; third, 'to supply automatic means for stopping the movementof the conveyer-apron when it has arrived at the limit of its dis-'eharging movement; fourth, to use suitable adjustable means fortightening up the con-- Voyer-apron; and lilith, to variously adapt saidimprovements to he conveniently used in connection with specialmechanism adaptof the machine. achieved by the mechanisn'i and meanswhich are hereinafter fully described and claimed, and which areillustrated in the accompanying drawings, in which;

Similar numerals refer to similar parts throughout the several views.

The \w.gon-hox'34A is connected to and supported by the parallellongitudinal sidebeams ll. 'lhosaid beams rest on holsters, which inturn are supported by the front and rear axles of the front and rearcarrying-wheels 107 and respectively. The 'forward part of the frame ofthe box 3ft is undercut lo allowY of the clearance of the front-wheels10'( in moving thereunder in turning the vehicle about. The rear end ofthe box is closed, while a distributor-drum 18 is secured to atransverserotatable shaft 20, the latter'being mounted aboutintermediately between the frontand rear-carrying Wheels, but the drumWorkingl in the open front end of the box. The saiddrum is adapted to berotated forwardly, so as to eject the contents of said box beneath itand just to the,rear of the front-carrying wheels.

The box 34- conlains a movable ('.onveyerapron, composed of transverseparallel slats 3h seoured at. each end to parallel longitudinal endlesssin-oclurt-chuins ,111. The chains are carried under the rear end of thebox on sproclwt-idlers :lli mounted on the ends of a transwrse rotatableshaft 35, the ends ot' the latter being' mounted in bearings 94 on therear ends of iuljustable bracketplates 37. Each'plate 37 is scoured tothe Wagon-box by a bolt passed through the Wagon-box, then tl'irough aspacing-block 9i, then through said plate and secured by a nut 95. Thebolt 92 referred to passes through the plate 37 by way of a longitudinalslot 9G, the latter permitting longitudinal adjustment or' the platealong` the block. The fomvard end of the plate 37 has a flange 108, witha notelied seat 97 in the upper edge o'lfthe latter lor a horizontalbolt 90, the rear end oi the latter being` threaded to receive a nut $3,and said bolt being passed through a horizontal` orifice in the blockSil. ly this moans the shaft is supported, and the latter may ,be.shifted longitudinally by turning the holt 90, 'when it is desired totighten the conveyerchains 111. The for Ward ends ot the. chai ns lllare passed over 30 the conveyer-apron 38, and has its outer end and atits rear end to said lever 61.' The hand-lever 41 may be shifted anappropriate distanceforward= or back to cause the members 114 and 115 tocontact withv and lift toa desired degree the driving-pawls 5() and 52'so as to correspondingly vary the length oftheir driving stroke on theratchet-wheel. When the members 114 and 115 are moved forward to thelimit they lift the pawls away from the'teetli of the ratchet-wheel,which causes the latter to come to a stop.

The drivingpawls aforesaid may be caused to become disengagedautomatically from theteeth of the ratchet-wheel by 'the followingmeans, when the pusher 16 of the conveyer-apron 38 has arrived at theforward limit of its course. A slideway 48 is attached to an upright 13Secured to thelefthand' side of the wagon-box. A slide-bar 44j, whoseforward end is pivoted to the handlever 41 at 43is adapted to slidehorizontally through said slideway. The rear free end of said' slide-barhas a Islot 117 through which a bolt 53 is inserted and' secured througha slide-head 54. By this means the length of said slide-bar may bevaried' to a desired adjustment. The numeral 65 desifrnates acontact-arm which projects laterally from the pusher 16, the latterbeing connected to without the box bent downward so as to enter' the.plane of movement of the slide-bar 44. Then the conveyer-a 'ron 38 hasmoved forward to the end of its orward course, the

rejection 65 has contacted with and pushed orward the slide-bar '44 withthe hand-lever 41, the connecting-rod 4G and the lever ($1, and socaused the members` 114 and 115 to lift the driving-pawls and stop the,movement of the ratchet-wheel and the apron. ln moving forward, thecatch 99 of the lever 41 clicks over the teetl1 100 of the` rack 42, andbecomes seated between such teeth at the end of stroke, thus holdingrthe pawls away from the ratchet-'wheel-L- I have adopted a device formoving backl the conveyor-apron as. follows. bell-crank lever Q1v isfulerumed on the right-hand end* ofthe shaft The forward member ofsaidl'ever is pivoted atlOl to the rear' end of a` connecting;- rod 9whose forward end is likewise pivoted at 10 to a lever'S. The'lever 8is-pivoted at its lower end on a studv 12 projecting" from the-frame 11,andv has' `a pedal at its Lipperend` for the use of the operator.

The rear member of the bell-crank,leverA 21y has a longitudinal slidewayT3 adap'trtlto receive an" adiustabl slide 70, the latter be- Zontal`bracket bearing;v for said idler, said ing slotted at`71 to receiveabolt. 72 extending" from saidrear member. '.lhe slide 7() has' atransverse bearing-orifice 1n` winch is seated' a laterally-adjustablepivot-shaft 25 and the latter'is seeurlf to said slide by a v Set-screw82.` A hub 1li carrying'` separated sprocket-wheels 69 and" 26 isrot-atably mounted on said shaft 25, and a. sprocket- .cham 24operatively connects the sprockets 69 and:y 22. The sprocket-wheel'liesl in the plane of the sprocket-chain 17 and'- below it, and may beshifted upward intol operative engagement with said chain 17, when thelever 8 is thrust forward.l When thefoot of the operator is removed romthe pedal of' the lever S, the weight of the mechanism connected to therear member of the lever 21 lwill cause the sprocket-wheel? to becomediscause the members 114 and 11I5xto drop from wheel to be driven withthe conveyer-apron i forward.

The hand-lever 2, which-is` pivoted to boxat 5 and works in the"rack-4*, is also pivotally connected: at 6 to tlie forward end of theeonnectin'frlrod 7,- whose rear endI is pivoted at 14 to Ztzhe crank `onthe rock-shaft 15, and when said liand-lever 2 is shifted forward, the'rock-shaftis turned to throw inward the upper end of the lever 17,-whichcauses the'- latters fork 28 to move the hub 68 outwardy andthusdisengage the teetlr of said hub from the teeth on the outer face ofthe sleeve 80., The sproeket-wheelBO then becomes idle on the shaft`29,and the rotation of the distributilig-drum 18 and the movement of theapron are stopped; When the lever 2 is 'thrown backward',` the alcovedescribed process is reverse/di7 andthe drum 18 again set in rotation.

The adjustability of the sprocket-wheels on the. shafts Q9, 25, 23 and20 as shown, laterally, permits of the use of .the mechanism with boxesof different widths, or earrying-wheels (litlerently spaced apart.

the

l Ots The forward part of the wagon-box is closed by arearwardly-projectingscreen 3 to protect the drivers seat 1 fromImaterial thrown to the Jfront bythe distributingdrum 1S.
